User authentication

After creating your users, you will need to authenticate them with the server.

You can do this with a combination of the username and password authentication method, and the get user APIs.

To set up authentication with the default database, we will pass a verifyPassword function to the server, and use the database APIs to verify our user.

Example

import CollabServer from '@pdftron/collab-server'
import CollabDatabase from '@pdftron/collab-db-postgresql';

const db = new CollabDatabase({
  ...params
})
await db.connectDB();
const resolvers = db.getResolvers();

const server = new CollabServer({
  ...otherParams,
  resolvers,
  verifyPassword: async (username, password) => {
    const user = await db.getUserByUsername(username);
    if(!user) {
      return false; // username is invalid / user not found
    }

    // remember that the password in the DB is hashed!
    const hashedPassword = user.password;

    // validate the password with your own logic
    const passwordIsValid = validatePassword(hashedPassword);
    return passwordIsValid
  }
})

db.setServer(server);
server.start();
